A significant solar event is captivating sky watchers across the southern United States. A series of coronal mass ejections (CMEs) from the sun are creating stunning displays of the aurora borealis. This phenomenon is currently visible in states as far south as Texas, Alabama, Georgia, and northern Florida.
Solar Storm Overview
The Space Weather Prediction Center has issued a G4 “severe” geomagnetic storm watch for Tuesday and Wednesday. G4 represents the second-highest level on a five-step scale that evaluates geomagnetic storm intensity.
What Causes the Northern Lights?
Geomagnetic storms are sparked by solar wind penetrating Earth’s magnetosphere. When charged particles from the sun collide with atmospheric gases, they create the breathtaking curtains of green, red, and purple light that typify the northern lights.
Viewing Conditions
In various regions, including middle Tennessee, conditions are ideal for viewing this natural light display. Clear skies are expected, offering residents a remarkable opportunity to experience the beauty of the auroras.
- Affected States: Texas, Alabama, Georgia, North Florida, Tennessee
- Storm Intensity Level: G4 (severe)
- Expected Duration: Storm may ease slightly by Wednesday but remain elevated through midweek.
Potential Impacts of the Solar Storm
While the northern lights are a remarkable sight, the G4 storm does pose some risks. Potential impacts include:
- Voltage control problems in power systems
- GPS navigation errors
- Intermittent issues with radio and satellite operations
Fortunately, most individuals are expected to only experience an awe-inspiring sky. This event serves as a reminder of the sun’s powerful influence on our technological world.
